In this post we are going to discuss that how can we convert GeoTIFF to AAIGrid data format.

GeoTIFF is a public domain standard which allows georeferencing information to be embedded within a TIFF file. GeoTIFF files also includes map projection, coordinate systems and datums data to establish the exact spatial reference for the file.

AAIGrid or Arc/Info ASCII Grid is supported for read and write access, including reading of georeferencing transform and some projections. The projections support is quite limited. It is normally produced with the Arc/Info ASCIIGRID command.

Conversion of GIS data like GeoTIFF to AAIGrid can be so easy with the help of the online conversion tool like IGIS Map Converter.

Raster files are currently not available for processing in IGISMAP, thus the output AAIGrid file cannot be visualized in the map canvas. Instead it will be available for download in the Converted Files section.

Converted Files section from the dashboard contains the list of the details of all the conversion done in your account, providing both input and output data available for download their corresponding formats
